Are All Valves Closed Clockwise and Opened Counterclockwise?
In daily life, we use many valves. We might follow a simple rule: “Turn right to tighten (clockwise), turn left to loosen (counterclockwise).” But is this rule always true? Are all valves really closed clockwise and opened counterclockwise? The answer is: Yes, in most cases. But there is a very important exception. The General Rule: Righty-Tighty, […]
Read moreWhere Should a Check Valve Be Installed?
How is the installation location of a check valve determined? What is the difference between installing a check valve before the pump versus after the pump? Where is pre-pump installation suitable? Check valves are often used with other valves. So, where should the check valve be installed when used in combination with other valves? Let’s […]
Read moreGuide to Choose Sanitary Butterfly Valves
Sanitary butterfly valves are key parts in fluid control systems. They are widely used in industries with strict hygiene needs, like food, beverage, pharma, biotech, and cosmetics. These valves help control fluid flow accurately while keeping the product safe from contamination. Picking the right type and size is very important. It affects how well the […]
Read moreWhat to Do If a Sanitary Valve Leaks or Gets Stuck
Sanitary valves are essential parts of piping systems. Sanitary valves are used in pharma and food industries. When sanitary valves leak or clog, problems arise. Production can be put behind schedule. Product quality is compromised. Understanding why this happens and how to repair it is essential. Why a Sanitary Valve Could Leak and How To […]
Read moreWhat Does the Operating Condition of Sanitary Valves Depend?
The working condition of the sanitary valve depends on many factors, including working pressure and working temperature of the medium, variation of pressure and temperature, driving mode, the installation position of the sanitary valve, service cycle, etc. Working pressure and temperature Generally speaking, the higher the pressure and temperature of the sanitary valve, the worse the […]
Read moreThe Causes Leading to Damaged Valve Sealing Surface
Mechanical damage: There will be scratches, bumps, crushes, and other damages during the opening and closing of the sealing surface. Between two sealing surfaces, under high temperature and high pressure, there will be mutual penetration of atoms, resulting in adhesion. When the two sealing surfaces move along each other, they’re prone to be torn apart […]
Read moreWhat is a Hydraulic Control Valve Mechanism?
What are the functions of the hydraulic control valves? Hydraulic control valves are used to adjust the flow rate of hydraulic fluid in a hydraulic system. These valves have a port that is able to be adjusted so that the flow area may be changed to provide an alteration in the flow rate through the […]
Read moreWhat Are the Anti-corrosion Methods for Sanitary Valves?
Coating The coating is the most widely used anti-corrosion means, especially in sanitary valve products is an indispensable anti-corrosion material and identification sign. The coating is usually made of synthetic resin, rubber slurry, vegetable oil, and solvent, covering the metal surface, insulating medium, and atmosphere, achieving the purpose of anti-corrosion. The coating is mainly used in […]
Read moreCommon Failures of Automatic Valve
Four common failures associated with automatic valves are found at a high frequency in poorly performing control loops. These are Dead band, Stiction, Positioner overshoot, Incorrect valve sizing, and Nonlinear flow characteristic. Let’s take a closer look at each of these problems. Failure one: the valve is blocked up. The reasons are: 1. The control channel […]
Read moreFAQs in Using Valves
1. Why is the sanitary double seat valve easy to oscillate when working? For single-core, when the medium is an open type, the valve stability is good; when the medium is a closed type, the valve stability is poor. The double seat valve has two spools, the lower spool in the flow closed state, and the […]
